Acculturation orientations of competing host communities toward valued and devalued immigrants     

Annie Montreuil  Richard Y. Bourhis   《Int J Intercult Relat》2004,28(6):507-532

This study explored how members of competing host communities may endorse different acculturation orientations towards valued and devalued immigrants settled in the bilingual city of Montreal. Francophone (N=422) and Anglophone (N=401) host community students from low-, medium- and high-ethnic diversity colleges completed the host community acculturation scale (HCAS) along with a questionnaire monitoring a range of social psychological correlates of acculturation orientations. Results showed that Anglophones were more integrationist and individualist and less assimilationist than Francophones. Both Francophones and Anglophones were more integrationist and individualist and less assimilationist, segregationist and exclusionist toward valued than devalued immigrants. Attending a multiethnic college had no influence on respondents’ acculturation orientations. The more welcoming acculturation orientations of Anglophones compared to Francophones was corroborated by results obtained with immigrants attending the French and the English colleges. Social psychological profiles of the respective acculturation orientations were similar across both host communities thus supporting the construct validity of the HCAS. Attitude toward co-national outgroup was a significant determinant of each acculturation orientations, suggesting that intergroup relations between rival host communities has an impact on acculturation orientations toward immigrants.  相似文献

色彩对运动能力的影响及其在体育运动中的应用     

汤盈  侯天德 《哈尔滨体育学院学报》2006,24(4)

心理学研究表明:在人的感觉器官中,视觉的信息量最大,而色彩是引起产生直接反应的一种视觉刺激。在体育比赛或训练中,色彩直接影响人的心理、生理状态和情绪变化,继而影响运动员的运动效果和运动成绩。随着2008年北京奥运会的临近,我们应科学准确地利用色彩在体育运动中的积极作用,发挥运动员的运动潜能,提高运动成绩。  相似文献   

Investigation of Poor Academic Achievement in Children with Duchenne Muscular Dystrophy     

V. J. Hinton  D. C. De Vivo  R. Fee  E. Goldstein  Y. Stern 《Learning disabilities research & practice》2004,19(3):146-154

Duchenne Muscular Dystrophy (DMD) is a neurogenetic developmental disorder that presents with progressive muscular weakness. It is caused by a mutation in a gene that results in the absence of specific products that normally localize to muscle cells and the central nervous system (CNS). The majority of affected individuals have IQs within the normal range, generally with lower verbal than performance IQ scores. Prior work has demonstrated selective deficits on tests of verbal span and immediate memory. For the current study, 26 boys with DMD (and normal intellectual function) and their unaffected siblings were evaluated. Paired comparisons demonstrated that the children with DMD had significantly poorer academic achievement scores than their siblings, even though their vocabulary levels and home and educational environments were comparable. Children with DMD also had more behavioral concerns, physical disabilities, and poorer verbal memory spans. Linear regression indicated that behavioral concerns, executive function, and physical disability did not contribute substantially to academic performance, whereas performance on verbal span did. DMD presents with a selective developmental aberration in verbal span that has wide‐ranging consequences on learning skills.  相似文献
